'nrionzme MACHINE.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, AGEORGE L. MAYES, of Bualo, in the county of Erie,and-State of New York, have invented certain new and useful improvements lin Brouzing Machines; and I do hereby declare that the 'following description of the construction and operation thereof -i's suiiiciently clear and exact to enable others skilled intheartto make and'use the same,vrefereuce being hadtothe annexed drawings, making a part ofthis specification, in which Figure 1 is la. longitudinal section. Figure 2, a. plan view. Figure 3, a side elevation. Figure 4,' a plate of glass and-frame representing a part of the transparent top of the machines. The nature of my .invention consists' in, rst, the employment of avert'ical revolving shaft, provided with arms atthe lower extremity, upon which are fastened one or more brushes, composed of fur or other suitable' material, in combination with suitable feeding 'mechanism of a machine for bronzing printed sheets of paper or other equivalent material; second, in combination, with the mechanism of a' bronzing machine, of one or more lights of glass, or other transparent substance, for the purpose of presenting to ,view the working of the machinery inside ythird, the use' of a grooved revolving roller for distributing the bronze, or itsfequvalent,

when used in combination with a suitable box for holding the bronze, and a brush or b rushes`for`receiving and distributing it; `fourth, in combination with the endless apron, upon which the cardfboard or paperis carried through the inachine,rof al thumb-screw and box so arranged l that said apronl may be loosened or tightened, as desired; fth, in the employment of adjustable lfeedwheels, which runl upon the. margin of a'pri'nte'd sheet when carried along by the endless apron, when said wheels are used in combinationfwith a belt or tape made to run in a groove in each of said wheels; sxthiin making the revolving brushes and endless apron capable of being adjusted vertically by means of a set-screw, ol' its equivalent. v In igJI, Arepresents the vertical rotary shaf It receives its motion from the VpulleyrGr and belt I. E E are the arms. They areemade of one piece, and are fastened to the shaft A by the nut F. C I) are two pads or brushes. J d are two upright rods fastened one in the` centre of each pad or brush. They slip up into an aperture near the, end' of each arm, and are adjusted and fastened by the set-screws H H, as shown in iig. 2. The llower part of the shaft A runs in the box L L, which is made in two halves, and is screwed on to 'the cross` piece4 M by the screws N N N N, as shown in fig. 2. At the top it works in a box or 'aperture in the cross-piece M1. 0, in iig..1, is an end view of the roller for distributing the bronze, showing the form of the. groove, which runs along its entire length. O2 is an endrview of the box in which it works. It is placed crosswise on the machine, and is the lreceptacle for the bron'ze. Ois the cover. I is a roll, covered with fur, or. its equivalent. It is placed directly under the grooved rollO. AU, T, V, 'and W are also fur rolls. Q and S are two rollers, upon which the endless apron is moved.l R isla bed-piece, which is placed just under the endless apron Y. Y The letters A1 1eprcsent thefeed-wheels for holdingrthe paper, and X X are bands which run in the grooves in said wheels. The letters' B represent sot-screws for holding said wheels in `place upon thc'rods Bz'and B3.' The -cnds olf vthe rods B2 and B3 work in'reccsses made in 'the sides oi' the box G3. They receive their motion from thc endless apron. Y2 is a drawer, for receiving the -waste or surplus bronze. Z is a transparent cover, It slidcs'fin agroove made in the cross-piece M and in the lower Vside of the box O2, as shown at the points U3 and U4 in iig l. Z1, in fig. 4, represents another' transparent plate or frame. It slides along the top of the box in grooves made in cach side. This transparent top is important, as oftentimes expensive work is passed throughv the machine, which requires-to be carefully handled. By it the progress of the work is seen at all times, and

thus loss by the wrinkling or springing up of the paper is prevented. In gs. 2 and 3, C4 representan, thumbscrew for tightening the-endless apron. There are two, one on cach side of the box G3. 1They screw into boxes, oneof which is shown the inner dotted lines at C5 in iig. 3. Each is fastened to aplate similar to -the one shown at C6. The ends of theroll Q'work in said boxes. .The outer or larger square of dotted lines surrounding the box C5 represents an opening in the` sides of the machine forv said box to work in. '.lhere'are four of such openingsytwofor the-boxes of the roller Q, and two for the roller S. They are made large enough to allow both avei-tical and horizontal-movement to be given to lthe'roller Q, and avertical movementto'the .roller S. These boxes are adjusted vertically, and heldin place to the sides of the machine by the screws E6 and C7, as shown in fig. 3. In the plan view the bronze receptacle or box is left oi, so that the rollers'below it may be seen. The printed sheets to be bronzed are fed into the Amachine at the opening Ulf. They receive the bronze from the rollers U and P in their passage, which is distributed and rubbed on to the printed surfaces by the revolving brushes when the sheets move under them. As they continue on through the machine they are cleaned by the ArollsT, V', and W, and delivered from the month U2. The bronze dusted from the sheets lfalls into thedrawer` below', from whence it can be taken out and used again. The various parts of the machinery are moved by the crank the band I3, and wheel D1 moves the grooved roll O for distributingrthe bronze. The bands I7 and wheels B7 and B9 move the fur roll P; which, in connection with the wheel Esand band I", give motion to the Wheels E4 E5, pulley Gr, thevertical shaft A, and the wheels B5 and B", together with the fur rollers, endless apron, &c.

What I claiin as my invention, and desire to vsecure by Letters Patent, is` 1. The vertical' rotary shaft A and brushes C and D, as described, when used in combination with tho feeding mechanism of a machine for bronzing prin'teds'heetsof paper or other equivalent material.

2. In combination therewith of one or more lights of glass or other transparent substance, for the purposes specified. l

3; The grooved roller O, as and for the purposes described. 4. In combination with the endless apron Y,7oi` the-thumb-screws C4, lthe boxes C5, plate C5, set-screws Il?c and C7, as and for the purposes described.

' 5. The adjustable feed-Wheels A1, in combination with the bands or belts, as described. A
